由于地表泰加林(两伯利亚针叶林)、沼泽等的影响,在西伯利亚西部采用线状布井方式。上侏罗统(J_3)产层中油藏的分带很复杂,这就是90年代早期之前,在两西伯利亚西缘的Shaimsky区每钻三口井就会出现干井的原因。如果在油田范围内采用某些储集岩分区的沉积关系,开发钻井的结果可能会好得多。这些自然因素有:1.古盆地的水深;2.距碎屑物源的距离;3.沉积作用区的近似方位(Proximityof the area of deposition)。使用本文提供的图件,可以避免在砂岩尖灭区、砂岩过渡为泥岩区或砂岩存在的概率很低的地区钻井。
Due to the influence of the terrestrial Taiga (BELARIA coniferous forest), swamps, etc., a linear well-welling method is used in western Siberia. The zoning of reservoirs in the Upper Jurassic (J_3) formation is complicated by the fact that dry wells were drilled in all three wells in the Shaimsky area of the western Siberia before the early 1990s. If the depositional relationship of some reservoir zones is used within the field, the result of drilling may be much better. These natural factors are: 1. The water depth of the ancient basin; 2. The distance from the debris source; 3. Proximity of the area of deposition. Using the plots provided in this article, it is possible to avoid drilling in areas where the sandstone is extinct, where the transition of sandstone to mudstone or sandstone is probable.
